See Kate Bosworth's Stunning Engagement Ring from Michael Polish!

When Kate Bosworth accepted boyfriend Michael Polish's marriage proposal she also scored herself some major bling!

Unveiling her square-cut diamond via her WhoSay page, Bosworth, 29, thanked fans and friends for their kind words during her and Polish's happy time. "This photo was taken by my husband-to-be," the Straw Dogs actress tweeted Tuesday. "Thank you for all the wonderful engagement wishes. . . . We feel truly blessed."

Bosworth and her director beau, 41, who met on the set of Big Sur (due out later this year) made their debut as a couple at a Coldplay concert in August 2011 and confirmed their engagement one year later.

"On our first day in Seoul, my fiance, Michael Polish, and I venture out to discover Changdeokgung Palace," Bosworth wrote in a Vogue travel blog, before continuing on with her chronicle of their visit to South Korea this summer.
